T-shaped rigid framework cantilever beam bridge synchronous pushing displacement control closure method and cantilever beam bridge
The invention discloses a T-shaped rigid framework cantilever beam bridge synchronous pushing displacement control closure method and a cantilever beam bridge, relates to the technical field of bridgeerection, and aims to solve the technical problem of poor pushing effect at present. The closure method of a cantilever beam bridge comprises the steps that a plurality of pushing mechanisms are installed in a first closure opening and a second closure opening which are symmetrically distributed; the multiple pushing mechanisms in the first closure opening and the second closure opening are synchronously controlled by controlling the main box to conduct pushing synchronously; the two cantilever beams on the two sides of the first closure opening and the two cantilever beams on the two sides of the second closure opening are locked; and the first closure opening and the second closure opening are poured. A cantilever beam bridge is closed by adopting the closing method. According to the invention, the stress of each point at the end part of each cantilever beam is consistent, and a better pushing effect is realized.
本发明公开了一种T型刚构悬臂梁桥同步顶推位移控制合龙方法及悬臂梁桥，涉及桥梁架设的技术领域，以解决现在顶推效果较差的技术问题。该悬臂梁桥的合龙方法包括：在对称分布的第一合龙口和第二合龙口内均安装多个顶推机构；通过控制主箱同步控制第一合龙口内和第二合龙口内的多个顶推机构同步进行顶推；将第一合龙口两侧的两个悬臂梁锁定以及第二合龙口两侧的两个悬臂梁锁定；对第一合龙口和第二合龙口进行浇筑。该悬臂梁桥采用上述的合龙方法进行合龙。本发明使每个悬臂梁的端部的各点受力一致，实现了较好的顶推效果。
